CP Piston & Ring Set for Mini Cooper S N14 1.6L - Bore (77.0mm) - Size (STD) - CR (10.5) - Single

Forged from aerospace-grade 2618 aluminum alloy, these CP Pistons are built to handle the demands of a performance Mini Cooper S N14 1.6L engine. The 77.0mm standard bore size and 10.5:1 compression ratio are specifically chosen to work with the factory cylinder head, offering an improved performance profile without requiring extensive modifications. This set is designed for a single piston application, meaning you'll need to purchase the correct quantity for your engine build.

CP Pistons are well-known for their robust construction and attention to detail. Each piston features a deep valve relief to ensure proper clearance with your camshafts, a critical detail for engine longevity. The included rings are also selected to complement the piston's performance characteristics, contributing to a solid seal and efficient combustion. While these pistons are a solid option for rebuilding or upgrading your Mini's engine, please note they are not CARB approved and cannot be shipped to California.
